, a government of, and by, and for the people, entrusting each generation to keep safe our founding creed. and for more than two hundred years, we have. through blood drawn by lash and blood drawn by sword, we learned that no union founded on the principles of liberty and equality could survive half- slave and half-free. we made ourselves anew, and vowed to move forward together. together, we determined that a modern economy requires railroads and highways to speed travel and commerce, schools and colleges to train our workers. together, we discovered that a free market only thrives when there are rules to ensure competition and fair play. together, we resolved that a great nation must care for the vulnerable, and protect its people from life's worst hazards and misfortune. through it all, we have never relinquished our skepticism of central authority, nor have we succumbed to the fiction that all society's ills can be cured through government alone. our celebration of initiative and enterprise, our insistence on hard work and personal responsibility, these are constants in our character.
